  • Let a model instance choose appropriate view class using category. Is it good design?

    - by Denis Mikhaylov
    Assume I have abstract base model class called MoneySource. And two realizations BankCard and CellularAccount. In MoneysSourceListViewController I want to display a list of them, but with ListItemView different for each MoneySource subclass. What if I define a category on MoneySource @interface MoneySource (ListItemView) - (Class)listItemViewClass; @end And then override it for each concrete sublcass of MoneySource, returning suitable view class. @implementation CellularAccount (ListItemView) - (Class)listItemViewClass { return [BankCardListView class]; } @end @implementation BankCard (ListItemView) - (Class)listItemViewClass { return [CellularAccountListView class]; } @end so I can ask model object about its view, not violating MVC principles, and avoiding class introspection or if constructions. Thank you!

  • Oracle Applications Cloud Release 8 Customization: Your User Interface, Your Text

    - by ultan o'broin
    Introducing the User Interface Text Editor In Oracle Applications Cloud Release 8, there’s an addition to the customization tool set, called the User Interface Text Editor  (UITE). When signed in with an application administrator role, users launch this new editing feature from the Navigator's Tools > Customization > User Interface Text menu option. See how the editor is in there with other customization tools? User Interface Text Editor is launched from the Navigator Customization menu Applications customers need a way to make changes to the text that appears in the UI, without having to initiate an IT project. Business users can now easily change labels on fields, for example. Using a composer and activated sandbox, these users can take advantage of the Oracle Metadata Services (MDS), add a key to a text resource bundle, and then type in their preferred label and its description (as a best practice for further work, I’d recommend always completing that description). Changing a simplified UI field label using Oracle Composer In Release 8, the UITE enables business users to easily change UI text on a much wider basis. As with composers, the UITE requires an activated sandbox where users can make their changes safely, before committing them for others to see. The UITE is used for editing UI text that comes from Oracle ADF resource bundles or from the Message Dictionary (or FND_MESSAGE_% tables, if you’re old enough to remember such things). Functionally, the Message Dictionary is used for the text that appears in business rule-type error, warning or information messages, or as a text source when ADF resource bundles cannot be used. In the UITE, these Message Dictionary texts are referred to as Multi-part Validation Messages.   If the text comes from ADF resource bundles, then it’s categorized as User Interface Text in the UITE. This category refers to the text that appears in embedded help in the UI or in simple error, warning, confirmation, or information messages. The embedded help types used in the application are explained in an Oracle Fusion Applications User Experience (UX) design pattern set. The message types have a UX design pattern set too. Using UITE  The UITE enables users to search and replace text in UI strings using case sensitive options, as well as by type. Users select singular and plural options for text changes, should they apply. Searching and replacing text in the UITE The UITE also provides users with a way to preview and manage changes on an exclusion basis, before committing to the final result. There might, for example, be situations where a phrase or word needs to remain different from how it’s generally used in the application, depending on the context. Previewing replacement text changes. Changes can be excluded where required. Multi-Part Messages The Message Dictionary table architecture has been inherited from Oracle E-Business Suite days. However, there are important differences in the Oracle Applications Cloud version, notably the additional message text components, as explained in the UX Design Patterns. Message Dictionary text has a broad range of uses as indicated, and it can also be reserved for internal application use, for use by PL/SQL and C programs, and so on. Message Dictionary text may even concatenate together at run time, where required. The UITE handles the flexibility of such text architecture by enabling users to drill down on each message and see how it’s constructed in total. That way, users can ensure that any text changes being made are consistent throughout the different message parts. Multi-part (Message Dictionary) message components in the UITE Message Dictionary messages may also use supportability-related numbers, the ones that appear appended to the message text in the application’s UI. However, should you have the requirement to remove these numbers from users' view, the UITE is not the tool for the job. Instead, see my blog about using the Manage Messages UI.

  • Is OOP becoming easier or harder?

    - by tunmise fasipe
    When the concepts of Object Oriented Programming were introduced to programmers years back it looks interesting and programming was cleaner. OOP was like this Stock stock = new Stock(); stock.addItem(item); stock.removeItem(item); That was easier to understand with self-descriptive name. But now OOP, with pattern like Data Transfer Objects (or Value Objects), Repository, Dependency Injection etc, has become more complex. To achieve the above you may have to create several classes (e.g. abstract, factory, DAO etc) and Implement several interfaces Note: I am not against best practices that makes Collaboration, Testing and Integration easier

  • How often do CPUs make calculation errors?

    - by veryfoolish
    In Dijkstra's Notes on Structured Programming he talks a lot about the provability of computer programs as abstract entities. As a corollary, he remarks how testing isn't enough. E.g., he points out the fact that it would be impossible to test a multiplication function f(x,y) = x*y for any large values of x and y across the entire ranges of x and y. My question concerns his misc. remarks on "lousy hardware". I know the essay was written in the 1970s when computer hardware was less reliable, but computers still aren't perfect, so they must make calculation mistakes sometimes. Does anybody know how often this happens or if there are any statistics on this?

  • Java best practice Interface - subclasses and constants

    - by Taiko
    In the case where a couple of classes implements an interface, and those classes have a couple of constants in common (but no functions), were should I put this constant ? I've had this problem a couple of times. I have this interface : DataFromSensors that I use to hide the implementations of several sub classes like DataFromHeartRateMonitor DataFromGps etc... For some reason, those classes uses the same constants. And there's nowere else in the code were it is used. My question is, were should I put those constants ? Not in the interface, because it has nothing to do with my API Not in a static Constants class, because I'm trying to avoid those Not in a common abstract class, that would stand between the interface and the subclasses, because I have no functions in common, only a couple of constants (TIMEOUT_DURATION, UUID, those kind of things) I've read best practice for constants and interface to define constants but they don't really answer my question. Thanks !

  • Create many similar classes, or just one

    - by soandos
    The goal is to create an application that has objects that can represent some operations (add, subtract, etc). All of those objects will have common functions and members, and thus will either implement an interface or inherit from an abstract class (Which would be better practice, this will be in C# if that matters?). As far as I can see, there are two different ways of organizing all of these classes. I could create an addition class, a subtraction class, etc. This has the upside of being highly modular but the difference between classes is so minimal. I could create one class, and have a member that will say what type of operation is being represented. This means lots of switch statements, and losing some modularity, in addition to being harder to maintain. Which is is better practice? Is there a better way of doing that is not listed above? If it matters, the list of functions that should be supported is long.

  • Vocabulary: Should I call this apply or map?

    - by Carlos Vergara
    So, I'm tasked with organizing the code and building a library with all the common code among our products. One thing that seems to happen all the time and I wanted to abstract is posted below in pseudocode, and I don't know how to call it (different products have different domain specific implementations and names for it) list function idk_what_to_name_it ( list list_of_callbacks, value common_parameter ): list list_of_results = new list for_each(callback in list_of_callbacks) list_of_results.push(callback(common_parameter)) end for_each return list_of_results end function Would you call this specific construct a list ListOfCallbacks.Map( value value_to_map) method or would it better be value Value.apply(list list_of_callbacks) I'm really curious about this kind of thing. Is there a standard guide for this stuff?

  • Is it possible to modify a video codec + distribute it?

    - by Nick
    this is my first question on this particular stackexchange node, not sure if it's the most appropriate place for this question (if not, guidance to the appropriate node would be appreciated). the abstract: I'm interested in modifying existing video codecs and distributing my modded codecs in such a way as to make them easily added to a users codec library... for example to be added to their mpeg streamclip, ffmpeg etc. some details: I've had some experience modifying codecs by hacking ffmpeg source files and compiling my hacked code (so that for ex: my version of ffmpeg has a very different h.263 than yours). I'm interested now in taking these modified codecs and somehow making them easily distributable, so others could "add them" to their "libraries." Also, I realize there are some tricky rights/patent issues here, this is in part my motivation. I'm interested in the patent quagmires, and welcome any thoughts on this as well. ctx link: if it helps (to gauge where I'm coming from) here's a link to a previous codec-hacking project of mine http://nickbriz.com/glitchcodectutorial/

  • access to site owner not working

    - by Daveo
    I made a website it works for everyone except for the site owner, who cannot access the site. He gets a server could not be found error. I went to his house and the issue occurs for all of his devices (PC, laptop, iPhone using WiFi) when I turn WiFi off the iPhone it works. So I thought it was a problem on his router so I reset is router to default factory settings but it still does not work, I have flushed his DNS cache and his browser cache. But nothing seems to help. He cannot even PING the server using the domain name. However when he uses the IP address he can see the site fine. I looked in cpanel for an blocked IP addresses but cannot see anything. What could be stopping just him from accessing the site via domainname and not the IP address? Site details are: PHP, osCommerce it is hosted by site5 on my reseller account.

  • May I give a single class multiple responsibilities if only one will ever be reusable?

    - by lnluis
    To the extent that I understand the Single Responsibility Principle, a SINGLE class must only have one responsibility. We use this so that we can reuse other functionalities in other classes and not affect the whole class. My question is: what if the entity has only one purpose that really interacts with the system, and that purpose won't change? Do you have to separate the implementations of your methods into another class and just instantiate those from your entity class? Or to put it another way... Is it ok to break the SRP if you know those functions will not be reusable in the future? Or is it better to assume that we do not know if the functionalities of these methods will be reusable or not, and so just abstract them to other classes?

  • How to flag a class as under development in Java

    - by Usavich
    I'm working on a internship project, but I have to leave before I can finish up everything. I have 1 class that is not stable enough for production use. I want to mark/flag this class so that other people will not accidentally use it in production. I have already put the notice in Javadoc, but that doesn't seem enough. Some compiler error or warning would be better. The code is organized like this: [Package] | company.foo.bar.myproject |-- Class1.java |-- Class2.java |-- Class3.java <--(not stable) If there was a single factory class that calls those classes in public methods, I could have set the method to class3 as private. However the API is NOT exposed that way. Users will directly use those class, e.g. new Class1();, but I can't make a top-level class private. What's the best practice to deal with this situation?

  • What can I do when the interviewer doesn't know the answer to his/her own question?

    - by bjskishore123
    Yesterday I had a terrible experience in an interview. Interviewer asked me about pure virtual function. I said, It may or may not have definition in base class, but derived classes should provide definition unless they also want to be abstract class. But interviewer kept on asking that "Can pure virtual have definition !!! ???"... I said yes. Again he said "Pure ?" I said yes. It is allowed, derived classes can explicitly call that function if they want that particular behavior. He sent me out. I am sure that he doesn't know the fact that pure virtual function can have definition. How to deal with this kind of Interviewers ? After asking 2nd time, should i lie that it can't have definition ? :) Or i should stick to my words and loose the job opportunity ?

  • Don’t string together XML

    - by KyleBurns
    XML has been a pervasive tool in software development for over a decade.  It provides a way to communicate data in a manner that is simple to understand and free of platform dependencies.  Also pervasive in software development is what I consider to be the anti-pattern of using string manipulation to create XML.  This usually starts with a “quick and dirty” approach because you need an XML document and looks like (for all of the examples here, we’ll assume we’re writing the body of a method intended to take a Contact object and return an XML string): return string.Format("<Contact><BusinessName>{0}</BusinessName></Contact>", contact.BusinessName);   In the code example, I created (or at least believe I created) an XML document representing a simple contact object in one line of code with very little overhead.  Work’s done, right?  No it’s not.  You see, what I didn’t realize was that this code would be used in the real world instead of my fantasy world where I own all the data and can prevent any of it containing problematic values.  If I use this code to create a contact record for the business “Sanford & Son”, any XML parser will be incapable of processing the data because the ampersand is special in XML and should have been encoded as &amp;. Following the pattern that I have seen many times over, my next step as a developer is going to be to do what any developer in his right mind would do – instruct the user that ampersands are “bad” and they cannot be used without breaking computers.  This may work in many cases and is often accompanied by logic at the UI layer of applications to block these “bad” characters, but sooner or later someone is going to figure out that other applications allow for them and will want the same.  This often leads to the creation of “cleaner” functions that perform a replace on the strings for every special character that the person writing the function can think of.  The cleaner function will usually grow over time as support requests reveal characters that were missed in the initial cut.  Sooner or later you end up writing your own somewhat functional XML engine. I have never been told by anyone paying me to write code that they would like to buy a somewhat functional XML engine.  My employer/customer’s needs have always been for something that may use XML, but ultimately is functionality that drives business value. I’m not going to build an XML engine. So how can I generate XML that is always well-formed without writing my own engine?  Easy – use one of the ones provided to you for free!  If you’re in a shop that still supports VB6 applications, you can use the DomDocument or MXXMLWriter object (of the two I prefer MXXMLWriter, but I’m not going to fully describe either here).  For .Net Framework applications prior to the 3.5 framework, the code is a little more verbose than I would like, but easy once you understand what pieces are required:             using (StringWriter sw = new StringWriter())             {                 using (XmlTextWriter writer = new XmlTextWriter(sw))                 {                     writer.WriteStartDocument();                     writer.WriteStartElement("Contact");                     writer.WriteElementString("BusinessName", contact.BusinessName);                     writer.WriteEndElement(); // end Contact element                     writer.WriteEndDocument();                     writer.Flush();                     return sw.ToString();                 }             }   Looking at that code, it’s easy to understand why people are drawn to the initial one-liner.  Lucky for us, the 3.5 .Net Framework added the System.Xml.Linq.XElement object.  This object takes away a lot of the complexity present in the XmlTextWriter approach and allows us to generate the document as follows: return new XElement("Contact", new XElement("BusinessName", contact.BusinessName)).ToString();   While it is very common for people to use string manipulation to create XML, I’ve discussed here reasons not to use this method and introduced powerful APIs that are built into the .Net Framework as an alternative.  I’ve given a very simplistic example here to highlight the most basic XML generation task.  For more information on the XmlTextWriter and XElement APIs, check out the MSDN library.

  • Black screen with blinking cursor after dual boot install 14.04

    - by chillstream
    I have just installed Ubuntu 14.04 on my toshiba laptop along side Windows 7. When the menu comes up to choose which OS to boot into, I can easily boot into Windows 7. I cannot successfully boot into Ubuntu. All I get is a blinking cursor on a black/purple screen. I attempted the nomodeset trick, which was a bit more successful. I got a screen with a lot of code, but then it stopped with a blinking cursor at the bottom and wouldn't load anymore. As a last resort, would returning my laptop to factory settings get rid of linux and the partitions made to the drive? I already did this to my laptop when it was just windows, which is why I thought I might as well try to add Ubuntu. But it's a lengthy process, and if it won't get rid of the partitions and ubuntu, I won't bother. I appreciate any help ~many thanks

  • Dynamic Components

    - by Alex
    I am attempting to design a component-based architecture that allows Components to be dynamically enabled and disabled, much like the system employed by Unity3D. For example, all Components are implicitly enabled by default; however, if one desires to halt execution of code for a particular Component, one can disable it. Naively, I want to have a boolean flag in Component (which is an abstract class), and somehow serialize all method calls into strings, so that some sort of ComponentManager can check if a given Component is enabled/disabled before processing a method call on it. However, this is a pretty bad solution. I feel like I should employ some variation of the state paradigm, but I have yet to make progress. Any help would be greatly appreciated,

  • How to structure my java packages

    - by MightyPork
    I have a Java library, quite a huge one. I'm asking regarding Best Practices of structuring the source. For example, the logging sybsystem: Option 1: All in one package, named to sort nicely Log - static accessor LogMonitor - interface for log minotor LogMonitorBase - abstract class LogMonitorStdout - print log to console LogWriter - interface for file logger LogWriterSimple - log writer with just one log file LogWriterArchiving - log writer that handles old log files Option 2: Subpackages for Monitors and Writers, with better names Log monitors/LogMonitor monitors/BaseMonitor monitors/StdoutMonitor writers/LogWriter writers/SimpleLog writers/ArchivingLog The second maybe looks better, but perhaps it's not so practical from the java point of view (two extra packages). What do you suggest as the best practice here? A lot in one package, grouped by naming prefixes, or a lot of subpackages with better names?

  • Domain Model and Querying

    - by Tyrsius
    I am new to DDD, having worked only in Transaction-Script apps with an anemic model, or just Big Balls of Mud, so please forgive any terminology I abuse. I am trying to understand the proper separation between the domain model and the repository. What is the proper way to construct a domain object that is coming from a database, assuming the (incredibly simplified) need to query for objects by status (returns enumerable), or by ID. Should a factory be building the objects, exposing methods for GetByStatus() and GetByID(), using a DIed repository? Should a repository be called directly, knowing how to build a domain model from the DTO? Should the domain model have a constructor for get by ID, using a DIed repoistory to load the initial state, using some other (?) method for the list? I am not really sure what the best way would be, and this question has an answer advocating each one (these are certainly mutuallu exclusive).

  • Is ROA a specific form of SOA?

    - by JohnDoDo
    I have read somewhere that ROA (Resource Oriented Architecture) is SOA (Service Oriented Architecture) with specific constraints added. SOA is the abstract term and that ROA is an implementation of SOA with all of the constraints of RESTful services (SOA = concept, ROA = concept + implementation details). I also had my share of posts saying that ROA is REST and that SOA is SOAP and going into the same more or less pertinent comparisons between the two (SOAP and REST that is) etc etc. So just to clear up my confusion: Is ROA a specific form of doing SOA?

  • Looking to create a website ... need assistance on what technologies to use!

    - by rsala004
    First off, My group and I don't have any experience with databases or anything of that sort, only programming (not web-programming), so this post is just me wondering what things I should start researching and possibly some referral to a hosting company. The abstract idea is to have a list of things, each categorized, and each item with user-submitted reviews (made by users who are signed up with the website). Would absolutely everything be stored on a SQL database? (the long text reviews for example) Does anyone have any suggestions on some 'web frameworks' we could use to jumpstart us? What should our absolute first step be? (I was thinking about first designing the basic database? so we have something to work around...?) Should we worry about which host we choose right now, any recommendations? (would it be a trivial task to switch hosts in the future?) Thanks again, any help is appreciated!
